A synthesized Schiff base 2-acetylthiophene semicarbazone ( 3 ) was used for the preparation of Ni 2+  selective polyvinyl chloride (PVC) membrane electrode. The prepared electrode with the optimized composition, PVC: 3 :sodium tetraphenylborate:di-n-butylphthalate as 33:6:3:58 exhibited a Nernstian response over the working range of 5.0 × 10 −6 –5.0 × 10 −2  mol l −1  with a slope of 29.0 ± 0.3 mV/concentration. The electrode showed good selectivity towards Ni 2+  with respect to several metal ions in the pH range of 2.5–10.0 in &lt;15 s with a detection limit of 4.7 × 10 −6  mol l −1 . The electrode showed the additional benefit of working in partially nonaqueous media having up to 15% (v/v) methanol or ethanol. This electrode was also successfully applied in Ni 2+  ion potentiometric titration with ethylenediaminetetraacetic acid as an indicator electrode.
